### Logging conventions
|
|
|
|
A log message (the string/format passed to `Info`, `Error`, `Debug` etc, as well as their `Sprintf` counterparts) should
|
|
be a descriptive message about the event and may contain specific identifying characteristics. Regardless of the
|
|
level of detail in the message identifying characteristics should always be included via `WithField`, `WithFields` or
|
|
`WithError`
|
|
|
|
If an error is being logged use `l.WithError(err)` so that there is better discoverability about the event as well
|
|
as the specific error condition.
|
|
|
|
#### Common fields
|
|
|
|
- `cert` - a `cert.NebulaCertificate` object, do not `.String()` this manually, `logrus` will marshal objects properly
|
|
for the formatter it is using.
|
|
- `fingerprint` - a single `NebeulaCertificate` hex encoded fingerprint
|
|
- `fingerprints` - an array of `NebulaCertificate` hex encoded fingerprints
|
|
- `fwPacket` - a FirewallPacket object
|
|
- `handshake` - an object containing:
|
|
- `stage` - the current stage counter
|
|
- `style` - noise handshake style `ix_psk0`, `xx`, etc
|
|
- `header` - a nebula header object
|
|
- `udpAddr` - a `net.UDPAddr` object
|
|
- `udpIp` - a udp ip address
|
|
- `vpnIp` - vpn ip of the host (remote or local)
|
|
- `relay` - the vpnIp of the relay host that is or should be handling the relay packet
|
|
- `relayFrom` - The vpnIp of the initial sender of the relayed packet
|
|
- `relayTo` - The vpnIp of the final destination of a relayed packet
|
|
|
|
#### Example:
|
|
|
|
```
|
|
l.WithError(err).
|
|
WithField("vpnIp", IntIp(hostinfo.hostId)).
|
|
WithField("udpAddr", addr).
|
|
WithField("handshake", m{"stage": 1, "style": "ix"}).
|
|
Info("Invalid certificate from host")
|
|
